What if 1.5kM wide asteroid hits the UK ..

[EarthLife]

This is apparently what would happen if a 1.5kM asteroid would hit the little UK island at 38000 mph (apparently happens once every 2.2 million years) ..

added speed

Think it'd be much worse than that. Tunguska was a small asteroid much much smaller and it didn't even impact the ground but affected an area the size slightly smaller than Luxembourg.

I imagine it would be game over for 99.999999% of humanity, and the tiny number of survivors would face years of struggles and suffering. Really really not good!

Clothes would catch on fire within 216KM but trees at 357Km. Pedantic I know given the situation as a whole but I'd have expected the other way round 🙂

I think air born explosions cause a larger area of devastation, it's why atom bombs are designed to go off at a certain height rather than allowed to hit the ground I think.

I think clothes catching fire will be the least of your worries.

I don't think we'd have anything at all to worry about from then on ;)

Yes the thermal radiation caused by friction as it travlled through atmosphere, then subsequent impact, causing yet more thermal radiation, would vaporise people, much sooner than the blast wave would hit them! Utterly horrific! But very real!

Yes apparently the blast wave rebounds from the ground, magnifying it's energies, making it even more destructive. That being said, if the asteroid was 1.5km in diameter, then it would reach the earths surface mostly intact.

Guess my otas could make some sort of home for a microbe in the far future.

What? I'm fully kitted out in Prada....

I suppose these answers lie somewhere within:

Wikipedia is not such a bad reference on stuff?

In a human species context, "so far so good"? 😁

This table shows how many asteroids are out there in each size class.

I'm not in the least worried 😊. Why? Because it'll never ha

I vaguely recall a journal article comparing the effects of a high yield ground vs airburst that mentioned that.

Anyone else found linked site to have a therapeutic value?

Hmm, I'm annoyed by XY - lets fling medium sized meteorite at their house and see what happens

 

[StevieDvd]

It'll probably happen on one of the few clear nights we have.

And I guarantee one of the last messages out of Shropshire before a 1.5km wide lump of primordial Nickel and Iron smashes into the countryside and unleashes forces on the planet that haven't been seen since the dinosaurs will be a  Facebook post: "Just seen a bright fireball in the sky, is it the comet?  It didn't look green."

Ample opportunity to image it then.

What filter would you recommend to photograph that? The Optolong Armageddon?

The Antlia ALP-T of course. Astrophotography Last Photo, Ta-ra!

I think you have a typo surely the Optolong Armadeddun.
